The effective tab width for the output window is hardcoded to 8 characters and
cannot be changed through the Options dialog (neither basic nor advanced options).
I'm afraid I don't understand it very well. Can you attach some screenshot?
Assume the following code: System.out.println("1\tword);
It will be printed in the output window
as the output window assumes a tab is 8 spaces long. For every editor in NB I
can define the number of spaces NB assumes for each tab character. This is not
possible for the output window. I'm referring to the option available at
Tools -> Options -> Advanced Options -> Editor Settings -> Java Editor -> Tab size
The output is generated by ant, so reassigning there. Hope it's the right place.
Reassigning to new module owner Tomas Holy.
